Elapsed Time: Automation Classes

Home |  Overview |  How Do I

This procedure shows how to calculate the difference between two CTime objects and get a CTimeSpan result.

To calculate elapsed time

1. Create two COleDateTime objects.
   
   
2. Set one of the COleDateTime objects to the current time.
   
   
3. Perform some time-consuming task.
   
   
4. Set the other COleDateTime object to the current time.
   
   
5. Take the difference between the two times.

   COleDateTime timeStart, timeEnd;
   timeStart = COleDateTime::GetCurrentTime();
   // ... perform time-consuming task
   timeEnd = COleDateTime::GetCurrentTime();
   COleDateTimeSpan spanElapsed = timeEnd - timeStart;
